Principal palletizing machine

Fully automatic high-speed high-level palletizer for up to 2400 units per hour for bags and boxes.

The PRINCIPAL high-level bag palletizer forms layers of bags which are fed into the unit by a belt conveyor and loads the layers on top of the pallet which is lifted by an elevator. After a pre-set number of layers is reached, the pallet is lowered and automatically transported away by a roller conveyor.

In order to facilitate an ideal and flexible layer formation, bags can be turned into a pre-defined position. This is executed by a servo motor driven overhead turning device. The bags can then be turned into an optimal position, so that stitching tabs are positioned inwards, or barcodes can be read from the outside of the layer.

The individual bags are pushed from the layer forming belt onto the load plates by a so-called layer pusher. The synchronous-belt drive of the pusher allows the exact positioning of the bags. The motor-driven front and side pushers guarantee a stable, rectangular layer.

The completed layers are slipped off the load plates onto the pallet in the elevator. The pallet gets pressed against the load plates once they are closed. This layer pressing maximises the stability of the pallet.
